Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 57% and getting smaller. The 21 days old Moon is in ♊ Gemini.
* The exact date and time of this Last Quarter phase is on 12 September 2009 at 02:16 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon is passing about ∠11° of ♊ Gemini tropical zodiac sector.
Lunar disc appears visually 1.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1941" and ∠1906".
Next Full Moon is the Hunter Moon of October 2009 after 22 days on 4 October 2009 at 06:10.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
The Moon is 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 119 of Meeus index or 1072 from Brown series.
Length of current 119 lunation is 29 days, 8 hours and 43 minutes. It is 2 hours and 6 minutes shorter than next lunation 120 length.
Length of current synodic month is 4 hours and 1 minute shorter than the mean length of synodic month, but it is still 2 hours and 8 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠20.3°. At beginning of next synodic month true anomaly will be ∠39.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
11 days after point of apogee on 31 August 2009 at 11:04 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 4 days, until it get to the point of next perigee on 16 September 2009 at 07:55 in ♌ Leo.
Moon is 369 251 km (229 442 mi) away from Earth on this date. Moon moves closer next 4 days until perigee, when Earth-Moon distance will reach 364 054 km (226 213 mi).
10 days after its ascending node on 1 September 2009 at 03:18 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next 3 days, until it will cross the ecliptic from North to South in descending node on 14 September 2009 at 20:56 in ♋ Cancer.
10 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the beginning to the first part of it.
13 days after previous South standstill on 28 August 2009 at 20:17 in ♐ Sagittarius, when Moon has reached southern declination of ∠-26.391°. Next day the lunar orbit moves northward to face North declination of ∠26.289° in the next northern standstill on 12 September 2009 at 04:36 in ♊ Gemini.
After 7 days on 18 September 2009 at 18:44 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
